Andy Murray led the way for men's seeds at the Wimbledon Championships with the second seed facing and beating a fellow Brit for the first time ever at a grand slam.
Murray put out good friend and practise partner Liam Broady, the world number 235, winning 6-2 6-3 6-4.
The world number two never lost a serve during his one-and-three-quarter-hour victory as he begins the bid for a second home grand-slam title.
Stan Wawrinka tamed US teenager Taylor Fritz 7-6 (7-4) 6-1 6-7 (2-7) 6-4 as the fourth-seeded Swiss who owns two grand slam titles works to surpass his Wimbledon best of a quarter-final.
The 31-year-old is playing his 12th-straight Wimbldon and 46th major in a row.
He will next take on Argentine dangerman Juan Del Potro, who beat Stephane Robert 6-1 7-5 6-0 for his first Wimbledon victory since 2013 due to wrist injury problems.
A seeded French pair advanced in straight sets, as number seven Richard Gasquet defeated Briton Aljaz Bedene 6-3 6-4 6-3 while 12th-seed Jo-Wilfried Tsonga stopped Spaniard Inigo Cervantes 6-4 7-6 (7-5) 6-4.
German Dustin Brown, who knocked out Rafael Nadal a year ago, advanced over Serb Dusan Lajovic 4-6 6-3 3-6 6-3 6-4 to set up a clash with Australia's Nick Kyrgios who beat Radek Stepanek.
Meanwhile Russia's Svetlana Kuznetsova got a late birthday present under Wimbledon's centre court roof with a 7-5 6-4 win over former world number one Caroline Wozniacki, who is projected to drop out of the top 50 with the defeat.
The veteran 13th seed's power undid the Dane, who had been seeking her first win at a grand slam this year after being dumped out of the Australian Open in the first round and missing Roland Garros due to injury.
The WTA women's tour said the 25-year-old, rated the best in the world in 2010 and 2011, could drop as low as 59, depending on other results, when the new rankings are released the day after the men's final.
Coming into the tournament ranked 45 after injuries to her ankle, knee and wrist, it was the first time Wozniacki, 25, had been unseeded at a major since the 2008 Australian Open and she was visibly gloomy after the match.
Women's number one seed Serena Williams eased past Switzerland's Amra Sadikovic 6-2 6-4 to move into the next round. The American defending champion is eyeing Steffi Graf's professional era record of 22 grand slam titles.
